Abstract

ABSTRACT Soil properties and classes can influence the occurrence of plants and the production of Brazil nut fruits and may have a different distribution between sites. This study aimed to evaluate the relationship of plants’ occurrence, production of Brazil nut fruits, and spatial variability of the properties in different soil classes in two Brazil nut stand in the state of Acre, Brazil. The study was conducted in two plots in two native Brazil nut stand, Cachoeira (CP01 and CP02 – [...]

Highlights

The extraction of non-timber forest products (NTFP) is a fundamental means of subsistence for traditional populations of the Amazon (Silva et al, 2016)

The occurrence of plants and the production of Brazil nut fruits (Bertholletia excelsa) were associated with the classes and the physical and chemical properties of the soil, pyxidium production differed between areas

Summary

Introduction

The extraction of non-timber forest products (NTFP) is a fundamental means of subsistence for traditional populations of the Amazon (Silva et al, 2016). Non-timber forest products are resources obtained in native forests, planted forests, or agroforestry systems They may be from plant or animal, including fruits, seeds, barks, fibers, essential oils, and latex, among others (Elias and Santos, 2016). Brazil nut (Bertholletia excelsa Bonpl.), endemic to the Amazon (Muller, 1981), is one of the main NTFP of the Amazon, with strong socio-economic potential. The extractivism of this species generates income for traditional populations and family farmers and establishes the commercialization of seeds between nearby cities and abroad (Ortiz, 2002). It is a species protected by law (MMA et al, 2017), and it is classified as vulnerable in the IUCN Red List of Threatened Species (Americas Regional Workshop, 1998)
